John Torrey

1796 (New York) – 1873 (New York)

Torrey’s association with his student Asa Gray began in the 1830s and led to their publication of ‘Flora of North America.’ He corresponded extensively with other botanists and naturalists, including Henry, Silliman, Parry, von Schweinitz, Hooker, Bentham, Rafinesque and Downing. He met the environmentalist Muir in 1872, the year before his death.
